A reader I will call M emailed me last autumn with what looked, at first, like a normal skincare question. She had a small constellation of closed comedones on her left jawline that nobody else could see. She had photographed them under raking light from her desk lamp. She wanted to know which acid would clear them fastest. The email was 1,800 words long. She had been working on these comedones for fourteen months.
I did not answer her about the acid.
I wrote back to ask how often she was thinking about the comedones, how many products she had bought in the last six months to address them, whether the time she spent looking at her skin in the mirror felt under her control, and whether she had ever talked to a therapist about it. Two of her answers concerned me. One of them concerned me enough that I wrote, gently, that I thought she needed a referral, not a product recommendation.
This is not a typical post for this journal. I do not write about mental health often because I am not a clinician and the territory is full of ways to be unhelpful. But body dysmorphic disorder (BDD) sits at the intersection of skincare and clinical psychiatry in a way that anyone giving skincare advice eventually runs into, and I have been increasingly worried about how often I see it in my inbox. So I want to write about what the literature actually says, what the referral threshold looks like in practice, and what I have learned about my own role as someone who writes about skincare on the internet.
What the studies actually show
The prevalence numbers are the part that surprises most people.
In the general population, BDD has a lifetime prevalence somewhere between 1.7% and 2.4% depending on the screening instrument. In cosmetic dermatology populations, it is closer to 9% to 15%. Phillips, who has been the central researcher in this field for thirty years, published a 2014 review in the British Journal of Dermatology that put the cosmetic dermatology prevalence at around 11% across pooled studies. Conrado and colleagues, in a 2012 study specifically on BDD in dermatology clinics, found a prevalence of 14% among patients seeking cosmetic procedures, compared to 6.7% among general dermatology patients.
These are not small numbers. If a busy cosmetic dermatologist sees forty patients in a week, the literature predicts that four to six of them will meet diagnostic criteria for BDD. Most will not have been diagnosed. Most will not be in treatment.
The diagnostic criteria, per DSM-5, are:
- Preoccupation with one or more perceived defects or flaws in physical appearance that are not observable or appear slight to others.
- Repetitive behaviours (mirror-checking, excessive grooming, skin-picking, reassurance-seeking) or mental acts (comparing one’s appearance with others) in response to the appearance concerns.
- The preoccupation causes clinically significant distress or impairment in social, occupational, or other areas of functioning.
- The appearance preoccupation is not better explained by an eating disorder.
The skin is the most common site of BDD preoccupation, followed by hair and nose. This is in every major epidemiological study on BDD. The skin is also the most accessible site for the kind of repetitive checking and product-purchasing behaviour that meets criterion 2.
The Conrado 2012 paper makes a point I want to highlight. Patients with BDD who seek cosmetic dermatology procedures rarely report being satisfied with the procedure afterward. Phillips reported in earlier work that around 90% of BDD patients are unsatisfied or worse following cosmetic intervention. The mechanism is not that the procedure failed. The mechanism is that the perceived defect was not the real problem, and resolving the perceived defect surfaces a new one. This is well established in the BDD literature.
What it looks like in skincare contexts
The clinical literature is one thing. What I see in my inbox is another, and I want to describe the pattern, with the caveat that none of this constitutes diagnosis and that the threshold for referral is always going to be a judgment call rather than a rule.
The pattern includes some combination of: an extremely detailed description of a small or non-visible skin feature, photographs taken under non-standard lighting (raking light, magnification, mirror photos at unusual angles), a history of many products tried for the same concern without satisfaction, time spent looking at the feature in the mirror that the reader describes as outside their control, avoidance of social situations because of the skin concern, and a fixation that has persisted for many months or years despite the feature being objectively mild or invisible.
No single one of these is diagnostic. People without BDD photograph their skin under raking light. People without BDD try many products. The signal is the cluster, and especially the criterion 3 component (distress and impairment).
The signal that escalated my concern with M was that she had cancelled two work trips in the previous year because of the comedones, and that she had stopped seeing one of her closest friends because the friend “did not understand”. That is criterion 3 territory. It is not a skincare problem with a skincare solution.
The part I want to be careful about
I want to push back on something I see in skincare and dermatology spaces, including spaces I respect.
The pattern is to treat BDD as a label you slap on the difficult patient, the one who is never satisfied, the one who keeps coming back. This framing makes the clinician feel better and makes the patient feel worse. It also misses the point. BDD is not “the patient is difficult”. BDD is a serious psychiatric condition with a 25-30% lifetime suicide attempt rate in studied populations (Phillips 2007, J Clin Psychiatry). It is treatable, primarily with SSRIs and cognitive behavioural therapy with exposure and response prevention. It responds to treatment. It does not respond to a better tretinoin protocol or a more expensive serum.
The skincare industry has a financial incentive that runs in exactly the wrong direction. A person with BDD will buy products. A person with BDD will respond to marketing that promises a fix for a perceived flaw. A person with BDD is, in commercial terms, a high-value customer. The industry does not have a mechanism to say “we do not want this customer”. I do not think individual brands are malicious about this. I think the structure is.
The skincare-content industry (where I work, and where you might be reading this) is in a similar position. A person with BDD reads a lot of skincare content. A person with BDD engages with detailed how-to posts. The incentive runs in the same wrong direction.
I do not have a clean answer to this. What I have decided to do, personally, is to flag the pattern when I see it, to refuse to give product recommendations to readers who describe what looks like BDD without first suggesting they talk to a clinician, and to write things like this post.
What I would tell my past self
If I could go back to the version of me who started writing about skincare and would, in good faith, answer every question with a product recommendation, I would tell myself a few things.
Not every skincare question is a skincare question. A small percentage are. The signs are usually visible to anyone reading carefully.
The right answer to a BDD-pattern email is not a better acid. It is a gentle, specific recommendation to see a mental health professional, ideally one familiar with BDD. The International OCD Foundation maintains a referral network. The BDD Foundation in the UK does similar work.
Saying “I think you should talk to a therapist about this” feels overstepping. It is overstepping less than recommending a tenth product to someone who has already bought nine.
If you are reading this and recognising yourself, that is a signal worth taking seriously. The condition is treatable. The treatment works. The standard of evidence for SSRI-plus-CBT for BDD is good. People recover. The first step is talking to somebody who knows what they are looking at, which is not me and is not a skincare blogger.
M wrote back a month later. She had seen a therapist who specialised in BDD. She was starting CBT. The comedones, she said, were still there. They did not bother her in the same way. I am not going to claim her therapy was caused by my email. She had probably been ready to take that step for a while. I am glad she did.
FAQ
How do I tell the difference between caring about my skin and BDD?
The distinction is in three things: the severity of distress (does the skin concern make you cancel plans, avoid intimacy, lose sleep?), the persistence over time (have you been focused on the same feature for many months despite no objective change?), and how much control you feel over your attention to it. Caring about your skin is normal. Loss of control over the attention is not.
Is BDD the same as being self-conscious?
No. Most people are self-conscious about some aspect of their appearance. BDD is a clinical condition with specific diagnostic criteria including significant impairment in functioning. The line is not “are you self-conscious” but “is your self-consciousness running your life”.
Can a dermatologist diagnose BDD?
Some can. Most do not have the training or the appointment time for a proper psychiatric assessment. The diagnosis is best made by a psychiatrist, psychologist, or other mental health professional. Many dermatologists do screen using a brief instrument like the BDDQ. If your dermatologist asks you screening questions about your appearance preoccupation, that is a good sign.
What treatments work?
The strongest evidence is for SSRIs at higher-than-usual doses (fluoxetine, escitalopram), often combined with CBT with exposure and response prevention. Cosmetic procedures do not work for BDD and may worsen it. The Phillips literature is the most readable summary.
I think this is me. What is the next step?
Find a mental health professional with BDD experience. The International OCD Foundation and the BDD Foundation maintain referral networks. Your GP can refer you. The condition is treatable. People recover.
